A rapid in vitro method has been developed to predict digestibilities of nitrogen, dry matter (DM) and energy in feed ingredients and mixed diets for swine. A total of 21 samples, including nine feed ingredients and 12 ...

Nine individual feed ingredients and 12 mixed diets were used in an attempt to select the most suitable regression equation for predicting energy value and nitrogen digestibility from chemical analyses. Samples were analyzed ...

Our objective was to characterize reproductive performance for sows nursed by only two to four pigs for the last 5 days of lactation. Litter size was reduced beginning at 2 (16 sows), 3 (15 sows), or 4 (15 sows) weeks after ...

Two feeding trials involving a total of 320 head of finishing pigs were used to evaluate the effect of feeding an antibiotic to three groups selected from within a farrowing group. Pigs were divided by weight into group A ...

One hundred and twenty weaned pigs were used to evaluate the effect of space allowance. Pigs were housed in a control environment nursery with woven wire flooring with 4, 6, 8, 10, or 12 head per 4' x 5' pen which allowed ...
